The highest heat index in the country was recorded in Guiuan, Eastern Samar on May 26, 2024 at 55ºC, according to state weather bureau PAGASA.
The said heat index broke the record made in Iba, Zambales on April 28, 2024 at 53ºC.
PAGASA said that heat indices at 52ºC and up are already considered at “extreme danger level,” which means heat stroke is imminent.
Further, PAGASA pointed out that heat index is the measure of the temperature that a person feels which is different from the actual air temperature. It is computed by factoring in the humidity and the air temperature.
Heat cramps and heat exhaustion are likely in areas experiencing heat index on "danger level," which is from 42°C to 51ºC, PAGASA added.
